This study discussed the harmony of Chinese Basketball Association (CBA). We found that inharmonious factors include the audiences violence, athletes violence, referees’ qualification and black whistle. Based on these studies we proposed several strategies for creating harmonious competition: the Basketball...

The movement of nodes has a great influence on the performance of protocols in mobile ad hoc networks. Mobility model is used to describe the movement of nodes, react the mobile characteristics really. In real circumstances, mobile devices are usually attached to humans ,so the movement of such devices...

A tree with complicated labels can widely represent objects in the real world. In this paper, the sum of matched pair similarity is used only to measure the similarity of such trees, while omitting inserted nodes and deleted nodes in the maximum mapping conditions of edit operations. The principle of...

A large-capacity information hiding algorithm for HEVC is proposed. We modify the intra prediction modes in 4x4 luminance blocks to embed secret information. According to the probability distribution of the statistical optimal prediction mode and suboptimal prediction mode, we are establishing a mapping...

Distributed video coding (DVC) is a coding paradigm that can shift the computational expensive task from the encoder to the decoder. Though in theory the reverse of encoder and decoder complexity does not cause coding performance degradation compared with traditional hybrid video codecs, the gap between...

The actual dynamic network environment urgently requires us to give full consideration to the non-precision of the network state when we design the QoS routing algorithm. Mainly by substituting the piecewise function for the probability constant which is chosen by ants when a route is selected, changing...
